header cluster and breadcrumb colour

Breadcrumb links rested at duck-forest and hovered to duck-teal; they now sit at the
hover colour, so the hover and its transition go with it. One shared component, so the
full browser and the dashboard widget both pick it up. The current folder stays
duck-dark semibold, keeping clickable and current distinct.

Header: the theme control leads the right cluster and names the theme it is wearing
rather than showing a palette glyph — with 227 of them, which one is on is worth reading.
It takes JobsIndicator's pill styling so the cluster stays one shape, and keeps its
colour on --header-fg rather than hardcoding white.

The jobs indicators and the rescan button are Super Admin only now. Cosmetic, and the
comment says so: /jobs stays reachable by URL and rescan is gated server-side, so
nothing here is load-bearing. Uses the same user?.role check UserMenu already makes in
this folder rather than adding a second convention.
